6 Claims. (01. 173-259) This invention relates to a cable terminal for 11 which is slightly tapered in form as illustrated a battery post and has for one of its objects to at 12. The terminal has a body portion 13 proprovide a construction which may be securely vided with an orifice 14 of generally egg-shape fastened to the post and yet easily released thereoutline, with a smaller end 15 and a large end 16, from even though there be corroding about the the small end being of a size to engage the post 11 5 contacting parts. 7 about substantially one-half of its circumference Another object of the invention is the provision with its walls tapered to fit the tapered post as of a terminal having an opening to receive the illustrated in Fig. 2. Where, however, a straight post so shaped that the wall of the opening at one post is used the wall will be formed to correspond end will engage with the post about substantially and fit the same. The large end of the body is 10 one-half of the circumference of the post and of a size to freely encircle the post therein and will be held in firm contact therewith by a permit the body to be lifted easily therefrom. threaded member extending through the opposite A wear plate 17 is positioned in the orifice 14 wall and engaging the diametrically opposite side and is of a length greater than the thickness of of the post, the end of the opening opposite'that the body"13 to project therethrough to facilitate 15 engaged being enlarged to loosely receive the post its position and this wear plate may be provided for releasing the same from contacting engagewith an arm 18 which extends out of the orifice ment prior to lifting the terminal from the post. and longitudinally thereof with a ring-shaped end Another object of the inventionisthe provision 19 through which a bolt 20 extends and has n 20 of a wear or clamp plate which will be continuthreaded engagement with the opening 21 in the 20 ally held in a desired position and may not bewall of the body.

together, which I have accomplished by pro- 1. A terminal for securing a cable to a battery viding an egg-shaped opening. Also I have probinding post comprising a body member having vided a wear plate which may conform to the an elongated orifice of generally egg-shape to reshape of the terminal and which will be held in ceive the binding post of abattery, means for conpositionby engaging the binding screw and thus' necting said member to a cable, .a set screw exis not capable of being separated or lost; and I tending through said member into said orifice have also so arranged the arm for receiving the and generally longitudinally thereof for forcing cable that it will be held in place without the the post against the end wall of said orifice, said use of solder or threaded means; and the followorifice being smaller at its end distant from said 59 ing is a detailed description of the present emset screw.

bodiment of this invention illustrating the pre- 2. A terminal fort securing a cable to a battery ferred means by which these advantageous rebinding post comprising a body member having sults may be accomplished. an elongated orifice of generally egg-shape with With reference to the drawing, 10 designates its side walls spaced apart a distance substantiala fragmental portion of a battery having a post 1y equalling the diameter of the binding post at its 55 small end and tapering to space the side walls a distance substantially greater than the diameter of the post at its larger end, and a set screw extending through said body member into said orifice at the large end thereof directed generally longitudinally thereof for forcing the post against the end wall of said orifice.

3. A terminal for securing a cable to a battery binding post, comprising a body member having an elongated orifice therein for receiving a binding post, a wear plate in said orifice for engaging the binding post, a set screw through said member for forcing said plate against the binding post, an arm on said plate, said arm extending horizontally outwardly from the top of said wear plate a substantial distance, and a ring shape portion on said arm for engaging the inner surface of the head of said set screw and through which said set screw extends.

4. In a wear plate construction, a plate having a curved section, an arm integral with said plate and extending from one edge thereof and at right angle thereto, said arm being of substantially the same thickness as that of said plate,

and of smaller width than that of the plate, said arm also having a substantial length, an enlarged circular portion at the end of the arm away from the plate and extending in the same direction as and parallel to the said plate, and a circular opening in said portion of the arm.

5. A terminal for securing a cable to a battery post, comprising a member having an elongated opening therein for receiving the post, an arcuate wear plate receivable in said opening and adapted to engage with the post to force the same towards one end of said opening, means-for adjusting said plate longitudinally of said opening and an extension on said plate projecting beyond said member whereby the plate may be grasped to position it relatively to said member.

6. A terminal for securing a cable to a battery post, comprising a member having an elongated opening therein for receiving the post, a set screw in said member extending through said member and longitudinally of said opening, an arcuate wear plate of a length greater than the length of the corresponding dimension of the member through which said opening extends and positioned in said opening and extending therebeyond a suflicient distance to be grasped and held, said set screw engaging said plate to force it against the battery post when inserted in said opening, and means for connecting said member to a cable.
